Capitola Almond Tree Early Ripening and Shell Hardness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an almond tree variety that produces a crop ripe for commercial harvesting and shipment in mid-August under the ecological conditions of the San Joaquin Valley in California, with characteristics such as a soft shell, low percentage of doubles, and a sweet kernel flavor, which existing varieties like 'Nonpariel' and 'Carmel' do not fully meet.
Innovation Solution
The 'Capitola' almond tree variety, discovered as a chance seedling and asexually propagated, produces a consistently good quality nut crop with a soft shell, low doubles, and a sweet kernel, maturing for harvesting and shipment around August 10-15, with a smaller, darker kernel compared to 'Nonpariel', and a shell that is softer than 'Carmel' but not as soft as 'Nonpariel'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the almond tree variety produces a soft shell, then it is easier to shell, but the shell may be too soft compromising storage and shipping quality
Solution Approach 1:
The Capitola variety optimizes the shell hardness parameter to achieve a balanced state - softer than Carmel for easier shelling but harder than Nonpariel for better storage and shipping quality. This parameter optimization resolves the contradiction by finding the optimal middle ground that satisfies both shelling ease and quality preservation requirements.
2Loss of time
If the almond tree produces a crop ripe for harvesting in mid-August, then it meets commercial timing requirements, but it may compromise other quality attributes
Solution Approach 1:
The Capitola variety adjusts the ripening time parameter to mature approximately 10-15 days earlier than Carmel (mid-August harvesting), while simultaneously maintaining consistent quality attributes including shell hardness, kernel flavor, and low double production through selective breeding and asexual propagation.
3Manufacturing precision
If the almond tree produces a low percentage of doubles, then it appeals to distributors and consumers, but it may reduce overall crop yield
Solution Approach 1:
The Capitola variety optimizes the double production parameter to achieve a low percentage of doubles (2-3%), which improves kernel uniformity and consumer appeal, while maintaining high overall productivity through vigorous tree growth and regular bearing patterns.

AI summary
A new and distinct variety of almond tree as described, and which is somewhat similar to the ‘Nonpariel’ almond tree (unpatented), but which is distinguishable therefrom by producing a small to medium sized kernel of high quality and having a sweet flavor.
